To wZZ whom it may concern/.-

Be it known that I, DENIS JOSEPH RING, of Lowell,'in the county ofMiddlesex, of the Commonwealth of Massachusetts, have invented a new anduseful Improvement in Machinery for Making Metallic Shells forCartridges of Fire-Arms; and I do hereby declare the same to bedescribed in the following specification and represented in the accompa-IO nying drawings, of which- Figure 1 is a front elevation of a machineembodying my invention, the nature of which is defined in the claimhereinafter presented. Fig. 2 is a top view, and Fig. 3 a transversesection, of the main rotary die'carrier of such machine. Fig. 4 is a topview, and Fig. 5 a transverse section, of the radiallynotched wheel andits actuator for intermittently revolving the shaft of the maindie-carrier. Fig.

6 is an end or bottom view of the series of punches as arranged at equaldistances apart in a circle in their carrier. Fig. 7 is a verticalsection, and Fig. 8 an end view, of a cartridge-shell as made by themachine.

e 5- In this machine,instead of a single main diecarrier and a series ofauxiliary diecarriers and a series of it punches and mechanism foractuating them, as represented in the United Patent No. 286,151, I havenot only a single main die-carrier and a single auxiliary die carrierhaving in each a series of tapering holes or dies arranged at equaldistances apart in a circle, but a series of punches arranged at equaldistances apart in a circle and directly over the main die-carrier, thepunches being generally in number corresponding to that of the dies ofthe main die-carrier, but variable in their lengths and diameters, andprovided With mechanism for moving them simultaneously relatively to themain die-carrier or into and out of such, my improvement saving thenecessity of having more than one auxiliary die-carrier and mechanismfor operating it. I 4 5 In the drawings the primary or main rotarydie-carrier is shown at A, and the auxiliary die-carrier at B, the firstpart being mounted on a vertical shaft, 0, and the second on anothersuch shaft, D. The main die-carrier is situated above and laps on theauxiliary diecarrier, so that the dies or holes of the former may bebrought successively directly over those of the latter as the twodie-carriers may be revolved. Furthermore, directly over the severalholes or dies of the main carrier is a series of punches, E E E", &c.,they being arranged at equal distances apart in a circle and projecteddownward from a carrier or block, F, fixed to a bar, M. These punchesvary in their lengths and diameters; but the dies (till the maindie-carrier are alike in form, and taper more or less from their upperto their lower ends. The firstpunch, E, is simply with its die to punchfrom a strip of metal a disk, and form it concavo convex or cup-shaped.6 a After the cupped blank has been carried around under the secondpunch, such blank by such punch and the die will be contracted andextended into the form of a cylindrical cup 01' an approximationthereto. It will be in like manner reduced by the succeeding punches anddies until by the last of the se ries of punches it will be driven outof the main die-carrier into one of the dies of the auxiliarydie-carrier. To this latter die-carrier there is to be suitably adaptedmechanisms for trimming and heading the cup-shaped blanks and expellingthem from the carrier. These mechanisms constitute no part of mypreCsentin'11: rovement, the header being shown at T. I

The two shafts C and D are connected by gears K and L, and there isfixed to the shaft 0 a radiallynotched wheel, G, to engage with anactuator, H. The said wheel G has six radial notches, 7), arranged in itperipherally, as shown, and at equal distances apart, the wheelperiphery between each two notches being recessed, as shown at c, to thearc of acircle whose diameter corresponds to that of a 0 circularsegment, (I, constituting part of the actuator H, and arranged, asshown, on a level with the notched wheel G. Besides this segment,theactuator is provided with an arm, a, to extend over the wheel G, andcarry a 5 pin or stud, f, to project downward into one of the radialslots 1) of the wheel. The actuator is fixed on a short vertical shaft,9, that is provided with a bevel-gear, 71 which engages with abevel-gear, t, arranged on a horizontal shaft, I. (See Fig. 1.) Theactuator during each revolution will, by means of the pin f and notch1), partially revolve the wheel G, and next will hold it in positionwhile the segment of the actuator may be turning in a recess, 0.

Above the shaft 1 is the driving-shaft L, that engages with the saidshaft 1 by means of four gears, pp q q, arranged as represented. Suchshaft L has upon it a fast pulley, 2-, and a loose pulley, 8, about theformer of which a belt from a suitable motor is to run, in order tocause the shaft to revolve. Eccentrics t on the shaft 1 connect with thebar M by means of their collars o and connecting-rods N, such bar beingsuitably guided so as to be capable of moving vertically in the frame Aof the machine.

In practice the main die-carrier may have near it mechanism for feedingto it the strip of metal as occasion may require.

In the operation of the machine all the punches descend at once into themain die-ear rier, each of whose dies, during each intermittentrevolution of it, will be brought under i the punches in succession,whereby each blank will be successively contracted and elongated,

and finally forced into the auxiliary die-car- 2 rier to be carriedaround by it and subjected to the action of the mechanisms for trimmingand heading the blank and expelling it from the machine.

I claim- 3 having dies arranged substantially as de- ,5

scribed, with the series of punches of different lengths and diametersarranged in a circle corresponding with the dies in the main diecarrier, and having the mechanism for operating them, essentially asrepresented.
